'第3行

我的程序如下：

DELIMITER $$

USE hsiedwzw_booking

CREATE PROCEDURE regi_email (IN email VARCHAR(255), counti OUT INT)

BEGIN

DECLARE bContinue INTEGER;

SELECT COUNT(*) INTO bContinue FROM parent_reg_email WHERE reg_email =email;

    IF bContinue=0;

THEN SET @counti=1;

    ELSE SELECT COUNT(*) INTO bContinue FROM ets_bookings WHERE c_email =email;

         IF bContinue=0;

         SET @counti=2;


         ELSE SET @counti=3;

END IF;

END
$$
DELIMITER;

Answer 1

此行中的错误需要更改为：

CREATE PROCEDURE regi_email (IN email VARCHAR(255),OUT counti  INT)

修改

#DEFINER=`root`@`localhost` is for your server ;; USE hsiedwzw_booking; DELIMITER $$ CREATE DEFINER=`root`@`localhost` PROCEDURE `activeFor_accounthead`(IN email VARCHAR(255),OUT counti INT) BEGIN DECLARE bContinue INTEGER; SELECT COUNT(*) INTO bContinue FROM parent_reg_email WHERE reg_email =email; IF bContinue=0; THEN SET @counti=1; ELSE SELECT COUNT(*) INTO bContinue FROM ets_bookings WHERE c_email =email; IF bContinue=0; SET @counti=2; ELSE SET @counti=3; END IF; END$$ DELIMITER ;
